Die Erfindung ist anhand der Figuren 1 und 2 erläutert. Es zeigenThe invention is explained with reference to FIGS. 1 and 2. It demonstrate

Mg. 1 ein Ausführungsbeispiel der Erfindung; Mg. 2 in vergrößertem Maßstab als Detail aus Fig. 1 ein Entlüftungsventil nach, der Erfindung (Schnitt B-G des Details A).Mg. 1 an embodiment of the invention; Mg. 2 on an enlarged scale as a detail from FIG. 1 a vent valve according to the invention (section B-G of detail A).

Am Boden des Rumpfes 1 eines Schiffes ist eine Kreiselpumpe 2 gelagert. Zur Aufnahme der Kreiselpumpe ist im Rumpf ein sogenannter Brunnenschacht 3 vorgesehen, der mit einem Brunnendeckel 4 verschlossen ist. Die Kreiselpumpe besteht im wesentlichen aus einem Läufer 5, der in bekannter Weise von einem Spiralgehäuse umschlossen ist. Im Ausführungsbeispiel dient die Kreiselpumpe sowohl zum Antrieb als auch zum Steuern des Schiffes. Zu diesen Zwecken ist das Spiralgehäuse um eine vertikale Achse schwenkbar unter einem Getriebegehäuse 7 gelagert, das seinerseits auf dem Brunnendeckel 4 befestigt ist.A centrifugal pump 2 is mounted on the bottom of the hull 1 of a ship. There is a so-called centrifugal pump in the fuselage to accommodate the centrifugal pump Well shaft 3 provided with a well cover 4 is locked. The centrifugal pump consists essentially of a rotor 5, which in a known manner from a spiral housing is enclosed. In the exemplary embodiment, the centrifugal pump serves both to drive and to control the ship. To this Purposes, the spiral housing is pivotably mounted about a vertical axis under a gear housing 7, which in turn on the Well cover 4 is attached.

Der Läufer der Kreiselpumpe wird von einem nicht gezeichneten Motor aus über übliche ebenfalls nicht gezeichnete Getriebeelemente sowie über eine Kupplung 8 und ein im Getriebegehäuse gelagertes Winkelgetriebe angetrieben. Zum Antrieb der Schwenkbewegung des Spiralgehäuses dient ein zweiter Motor 9, mit dem über bekannte Getriebeglieder, die ebenfalls im Getriebegehäuse gelagert sind, das Spiralgehäuse geschwenkt werden kann.The rotor of the centrifugal pump is driven by a motor, not shown, via conventional gear elements, also not shown as well as driven via a clutch 8 and an angular gear mounted in the gear housing. To drive the swivel movement of the Spiral housing is used by a second motor 9, with which via known gear members, which are also mounted in the gear housing, the volute casing can be swiveled.

Das Wasser wird durch eine Ansaugöffnung 10 angesaugt, vom Läufer in das Spiralgehäuse 4 gedrückt und durch eine bekannteThe water is sucked in through a suction port 10, from Runner pressed into the spiral housing 4 and by a known

Düse 11 ausgestoßen, so wird das Schiff od.dgl. angetrieben. Durch Schwenken des Spiralgehäuses und damit durch Änderung der Richtung der Düse kann das Schiff gesteuert werden.Nozzle 11 ejected, so the ship or the like. driven. The ship can be steered by swiveling the spiral housing and thus by changing the direction of the nozzle.

Pig. 2 zeigt als Deta'l A der Fig. 1 und als Schnitt entlang der Linie B-C ein Ausführungsbeispiel für ein Entlüftungsventil nach der Erfindung. In einer Wand 12 des Spiralgehäuses 6 ist eine Entlüftungsöffnung 13 vorgesehen. In die Entlüftungsöffnung paßt dichtend eine Ventilklappe 14, die mittels eines Gestänges 15 od.dgl. an einem Gelenk 16 so angelenkt ist, daß sie durch ihr eigenes Gewicht in die in Fig. 2 ausgezogen gezeichnete Lage fällt. In der anderen Extremlage verschließt die Ventilklappe die Ventilöffnung, wie das strichpunktiert eingezeichnete Gestänge zeigt. Am Brunnendeckel ist ein Entlüftungsrohr 17 vorgesehen.Pig. 2 shows as detail A of FIG. 1 and as a section along it the line B-C an embodiment of a vent valve according to the invention. A ventilation opening 13 is provided in a wall 12 of the spiral housing 6. Into the vent fits sealingly a valve flap 14, which by means of a linkage 15 or the like. articulated on a joint 16 is that it falls by its own weight in the position shown in Fig. 2 in solid lines. In the other extreme position, it closes the valve flap the valve opening, as shown by the dash-dotted linkage. On the well cover is a vent pipe 17 is provided.

Insbesondere beim Eintauchen der Kreiselpumpe in das Wasser, das geschieht bei der Montage und kann auch z.B. bei einem Zuwasserlassen des Schiffes geschehen, befindet sich beim Anfahren Luft in dem Spiralgehäuse. Während des Anfahrzustandes wird die Luft von dem geförderten Wasser verdrängt und kann durch die Entlüftungsöffnung 13 und das Entlüftungsrohr 17 entweichen. Wenn die Luft herausgedrückt ist, drückt der Staudruck des strömenden Wassers die Ventilklappe 14 gegen die Entlüftungsbohrung 13, diese wird geschlossen. Da sich das Gestänge 15 außerhalb des Spiralgehäuses befindet und die Ventilklappe im Innern des Spiralgehäuses bündig abschließt,Especially when the centrifugal pump is immersed in the water, this happens during assembly and can also be used, for example, with a When the ship is launched, there is air in the spiral casing when it starts up. During the start-up state the air is displaced by the pumped water and can through the ventilation opening 13 and the ventilation pipe 17 escape. When the air is pushed out, the back pressure of the flowing water presses the valve flap 14 against the Vent hole 13, this is closed. Since the linkage 15 is located outside of the volute and the The valve flap closes flush inside the volute casing,

stellt das Entlüftungsventil während des Betriebes keinen Widerstand dar. Das Gewicht der Ventilklappe kann durch eine nicht gezeichnete Feder ersetzt oder unterstützt werden.the vent valve does not set any during operation Resistance. The weight of the valve flap can be replaced or supported by a spring, not shown.
